Strange problem with a patch from the girl nextdoor electro house soundset
 

I was poking around in the girl next door electro house soundset off the virus website yesterday and I noticed that when I use the second patch in the set titled "DIRTY2" after I hit a note I get a very high pitched squeal (sounds like a very high pitch sin wave) that keeps going until I switch patches and play a few notes on a new patch. Sometimes if I keep hitting notes using the DIRTY2 patch it keeps making the squeal but the sound also loses all of it's character. After about 3 hits it just sounds like a burst of distorted noise (and not in the good sense). I can't reliably reproduce the degrading note quality, but the squeal happens every time so here's an mp3 of what I'm talking about:

Hi Sonis, loaded the MP3 into Wavelab and can clearly see the left channel is outputting a contant 7KHz triangle/sine tone.

My guess is that the filters may be set to "split" mode (meaning that the two filters are working independently of each other), and that one of the filters is (probably accidently) poorly configured to give you the high pitched resonant tone in just one channel.

I also reckon that the 'Filter Balance' may be set slightly skewed, meaning the high pitched tone leaks into the other channel slightly.

But basically I think you need to look at the filter section of both filters to see if there's anything there (such as one that's a band-pass with extremely high resonance, or similar) that could be causing it.

I don't have a TI so cannot load it up, unfortunately.

Nope not the filters, I wiggled the cutoff all over the place on both of them while it was making the noise and it didn't change at all. It's also not always in the left channel (although most of the time it is) I've gotten it to do it on the right channel a couple times and both of them one time.

Try to change the feed back of the phaser or turn off the phaser.

Phaser did the trick. I'm surprised that patch got saved in to the library with the feedback cranked all the way like that.

I'm glad you said "electro house soundset" at the end of that. LOL
